TIRE-SAVER 0R AUTOMOBILE-JACK.

To all whom it may concern:

Be it known that 1, CHARLES T. NELSON, a citizen of the United States, residing at Oakland in the county of Burt and State of Nebraska, have invented certain new and useful Improvements in Tire-Savers or AutomobileJacks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in jacks, and has for its principal object to provide a jack which is particularly adapted for use in connection with motor vehicles and the like, and is designed to lift the vehicle so that the tires clear the ground, thereby relieving them of any unnecessary strain.

Another object of the invention is to provide a device which will simultaneously lift both the front and rear axles of the vehicle,

and hold them against accidental movement.

A further object of the invention is to provide a novel form of lifting means, which is so constructed as to enable the user to lift the weight of the car at a minimum expenditure of energy.

\Vith these and other objects in View, the drawing illustrates in perspective a jack Windlass used in connection therewith, constructed in accordance with this invention.

Referring to the drawings by characters of reference, the numeral 1 designates one of the base members of the device, while the numeral 2 designates the cooperating base member. These base members are preferably formed of a suitable material, such as a plank of wood or the like, but it is to be understood that if so desired a frame of a suitable construction may be used.

Rotatably mounted near the ends of each of the base members 1 and 2 are the shafts 3 and 41, which are designed to be spaced from each other a distance equal to the distance between the front and rear axles of the vehicle.

Secured to the shafts 3 and 1 near their ends and within the space between the base members 1 and 2 are the lifting elements designated generally by the-numeral 5, each of which comprises the sleeve 6, which extends around the shafts and acts as a support for the arm 7. This arm 7 is provided with the reinforcing rib 8, and in cross sec- Specification of Letters Patent. Patented Sept 12 1916. Application filed February 5, 1915.

tion would resemble a T-iron. The upper end of the arm 7 extends beyond the end of the rib 8, as at 9, and forms a lip, which cooperates with the lip 10, in forming a saddle for the reception of the vehicle axle. Each of the reinforcing ribs of the lifting elements which are secured to the bar 4c, is provided with a transversely extending aperture near the sleeve 6, while each of the lifting elements 5 which are secured to the bar 3, are provided with two apertures in the reinforcing rib, which are designed to cooperate with the apertures hereinbefore mentioned.

A suitable connecting rod 11, having hooked ends is designedto connect the lifting element 5 by passing the hooked ends through their respective apertures in the reinforcing ribs. A suitable bail 12 is secured in the lowermost aperture in the'lifting ele- .to, provide a means by which the simultaneous operation of all of the lifting elements is attained.

The lifting mechanism used in connection with the jack comprises a suitable support, designated generally by the numeral 13, which may be the wall of a building or other suitable structure, but as illustrated comprises a pair of vertical bars 14, which are set into the ground and connected near the point where they enter the ground by the plate 15, which is provided with apertures therein near each end, through which the bars 14 extend. Pivotally mounted between the bars 14: at a point intermediate the ground and their upper ends, is a suitable bail 16, the use of which will be more fully hereinafter described. Rotatable between the bars, near their upper ends is the shaft 17 carrying thereon the winding drum 18. This shaft is provided at one end with crank 19 and at its opposite end with a suitable ratchet wheel 20, which is designed to cooperate with the pawl 21 to hold the shaft and drum against rotation in one direction. A suitable flexible member 22 is connected at one end to the drum 18, and passes over one of the pulleys of the double block 23, having a hook 24: which engages the bight portion of the bail 12. The opposite end of the flexible member is passed through the block 25 and connected to the hook 26, carried by the block. A suitable hook 27 is also carried by the block 25 and is designed for each other, thereby exerting pull on the bails 12 and 16, and causing the lifting element 5 to move to a vertical position. It is apparent that when the lifting elements are in a vertical position the vehicle axles will rest thereon and the wheels will be held clear of the ground, thus relieving the tires of the weight of the vehicle, and also permitting any repairs to be made to the wheels which might be necessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be undertsood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claim.

What is claimed is A jack of the class described comprising a pair of parallel base boards positioned at relatively spaced distances apart, shafts rotatably mounted in each end of said boards, lifting elements comprising sleeves arranged around the opposite ends of the shafts, arms formed on said sleeves extending upwardly therefrom, ribs formed on the faces of said arms the upper ends terminating short of the ends of the arms, lips formed on and extending laterally from the upper ends of said ribs forming supporting members, said ribs provided with openings, connecting rods secured by their opposite ends through the openings in the ribs of the same, a V-shaped bail secured by its arms to certain of said ribs and by its apex portion to a power applying mechanism whereby upon pull upon said hail, the arms will be raised in a vertical position simultaneously, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

CHARLES T. NELSON.
